Disclosed is a method for forming a catalyst bed for catalytic decomposition of hydrogen peroxide, which uses 3-D printing techniques to form a porous metal backbone and treating the surface of the metal backbone to activate the surface, wherein the metal backbone is formed of a noble metal or a manganese complex. Also disclosed is a rocket engine having a 3D printed catalyst for catalytic decomposition of hydrogen peroxide, a fuel store, an oxidizer store, and a rocket engine, wherein the oxidizer is a stabilized solution of hydrogen peroxide, and a 3D printed catalyst bed. L'invention divulgue un procédé de formation d'un lit de catalyseur pour la décomposition catalytique de peroxyde d'hydrogène, qui utilise des techniques d'impression 3D pour former un squelette métallique poreux et le traitement de la surface du squelette métallique pour activer la surface, le squelette métallique étant formé d'un métal noble ou d'un complexe de manganèse. L'invention divulgue également un moteur-fusée ayant un catalyseur imprimé en 3D pour la décomposition catalytique de peroxyde d'hydrogène, un réservoir de carburant, un réservoir de comburant et un moteur-fusée, le comburant étant une solution stabilisée de peroxyde d'hydrogène, et un lit de catalyseur imprimé en 3D.
